Marc like marque? (6)
I believe the answer is:
brandy
'marc' is the definition.
The answer and definition can be both things that one consumes for nourishment as well as being singular nouns.
Perhaps you can see an association between them that I can't see?
'like marque?' is the wordplay.
I cannot quite see how this works, but
'like' could be 'y' (similar in meaning) and 'y' is found in the answer.
'marque?' could be 'brand' (synonyms) and 'brand' is found within the answer.
No letters remain.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for brandy that I've seen before include "Strong alcoholic spirit" , "Marc, say" , "warmer?" , "Alcoholic drink" , "See 20" .)
